Marketplace Home Buyers review: Company will not stop sending me through mail

I have been receiving monthly mailings from this company for years even though I have never requested that they get in touch with me.
I have attempted to be removed from whatever lists they have, by telephone, email and online. They have ignored all of my requests which, in my opinion, is them giving me the middle finger.
I filed a complaint against them with the Better Business Bureau at least one and a half months ago and as of today they have ignored the complaint.
In addition to the mailings, I received a text message from them about wanting to buy my property. My phone numbers have been on the state and federal do not call lists since these lists came to be.
